Make your own 2.1 multimedia wireless Bluetooth amplifier or portable speaker with this 2 x 50W + 100W amplifier board. The board accepts 12 VDC to 24 VDC which makes it perfect for making home or mobile audio projects. Make your audio project truly portable by adding three to five 18650 Li-Ion batteries.
These boards are pre-tested and pre-assembled, which makes your project easy to complete. The on-board jacks, potentiometer, and screw terminals let you get this board powered up and playing music in minutes. Just connect your power source using a 2.1 x 5.5 mm DC power plug, a 3.5 mm stereo audio source, and run speaker wire from the six screw terminals to you speakers and you're done.
